Well, how do I install ISPConfig 3 if I only have one server, and that server is running ISPConfig 2??? Can I uninstall ISPConfig 2, then install ISPConfig 3? Then setup the webs and users, copy over their websites??
ISPConfig 3 is not an update for ISPConfig 2. ISPConfig 3 is a multi server control panel with virtual mail and FTP users which has different system requirements then ISPConfig 2. So you can not update a ISPConfig 2 system with ISPConfig 3 without formatting the server harddisk and do a complete reinstall of the operating system as described in the ISPConfig 3 documentation. The perfect setup guides for ISPConfig 2 are not compatible with ISPConfig 3.
